In the past few years new classes of gamma-ray emitters have been discovered, unlocking unprecedented views on cosmic ray sources and on the mechanisms responsible for particle acceleration and propagation.
In this talk I outline several such examples: 1) TeV haloes around supernova remnants, pulsar wind nebulae, and star clusters; 2) GeV-TeV emission from the recurrent nova RS Ophiuchi; 3) GeV emission from ultra-fast outflows in active galactic nuclei. The phenomenology of these objects is discussed in the light of the recent progress in modeling acceleration and propagation of energetic particles via kinetic plasma simulations.
